Definitions
- the present disclosure relates generally to inkjet ink compositions and methods of making the same.
- Secondary color inks have been added to ink sets in an effort to increase the color gamut of the printing system in which the ink sets are used.
- Many pigments included in secondary color inks are capable of forming images that exhibit some relatively good properties, yet at the same time exhibit other, relatively poor properties.
- some pigments generate images having good gloss and chroma, but relatively poor lightfastness (e.g., window, indoor, or outdoor) and/or poor ozonefastness; and other pigments generate images having poor gloss and chroma, but exhibit relatively good lightfastness and/or ozonefastness.
- secondary color inks based upon orange or red pigments generally deliver relatively good gloss and chroma.
- these inks may also exhibit relatively poor lightfastness (i.e., color fade resulting from light exposure) and ozonefastness (i.e., color fade resulting form air exposure).
- Printed images formed from these inks tend to suffer from red, green, blue or other color density loss (i.e., fade) upon exposure to various forms of light (e.g., indoor, window, etc.) or to air over time.
- orange and red inks formed with magenta and yellow pigments may be formulated to have good lightfastness.
- these inks also tend to exhibit lower chroma or pure color than inks based on a secondary color pigment.
- the mixed pigment inks e.g., those formed with magenta and yellow pigments
- Embodiments of the ink composition disclosed herein advantageously include a red ink that exhibits good to excellent lightfastness (window, indoor, and/or outdoor), enhanced chroma, good to excellent ozonefastness, or various combinations thereof.
- lightfastness refers to the durability of a print when exposed to light. Generally, when an ink is referred to as being “lightfast”, it has fade resistance.
- the term “window” when used in combination with lightfastness generally refers to more extreme lighting conditions, non-limiting examples of which include exposure to direct or indirect sunlight, filtered by glass.
- the term “indoor” when used in combination with lightfastness generally refers to less extreme lighting conditions, a non-limiting example of which includes exposure to direct or indirect artificial lighting.
- the term “outdoor” when used in combination with lightfastness generally refers to exposure to direct sunlight without any filters.
- ozonefastness refers to the durability of a print when exposed to air without intervening isolating (from air) media. Generally, when an ink is referred to as being “ozonefast”, it has fade resistance.
- Embodiment(s) of the ink composition disclosed herein include an ink vehicle and an effective amount of pigment red 168 (which is commercially available as Hostaperm® Scarlet GO or Scarlet GO transparent from Clariant International Ltd., located in Muttenz, Switzerland).
- pigment red 168 which is commercially available as Hostaperm® Scarlet GO or Scarlet GO transparent from Clariant International Ltd., located in Muttenz, Switzerland.
- an effective amount refers to the minimal amount of a substance and/or agent, which is sufficient to achieve a desired and/or required effect.
- an effective amount of an “ink vehicle” is the minimum amount required in order to create an ink composition, while maintaining properties suitable for effective inkjet printing.
- Liquid vehicle or “ink vehicle,” as used herein, refers to the vehicle in which colorant is placed to form an ink.
- ink vehicles may be used with the inks, systems, and methods according to embodiments disclosed herein. It is to be understood that the ink composition disclosed herein may be an aqueous based ink, an organic based ink, or combinations thereof.
- suitable ink vehicles include, but are not limited to water soluble polymers, surfactants (e.g., non-ionic surfactants, ethoxylated nonionic fluorosurfactants, etc.), solvents, co-solvents, buffers, biocides, sequestering agents, viscosity modifiers, surface-active agents, chelating agents, resins, and/or water, and/or combinations thereof.
- surfactants e.g., non-ionic surfactants, ethoxylated nonionic fluorosurfactants, etc.
- the red ink has an ink vehicle including water soluble polymers, SURFYNOL 440 (a non-ionic surfactant commercially available from Air Products and Chemicals, Inc. located in Allentown, Pa.), glyceryl polyoxyethyl ether, pyrrolidone, glycerol, diethylene glycol, 1,2-hexanediol, Zonyl® FSO (an ethoxylated nonionic fluorosurfactant commercially available from Dupont located in Wilmington, DE), a biocide (a non-limiting example of which is a solution of 1,2-benzisothiazolin-3-one, triethanolamine, and combinations thereof.
- water soluble polymers SURFYNOL 440 (a non-ionic surfactant commercially available from Air Products and Chemicals, Inc. located in Allentown, Pa.), glyceryl polyoxyethyl ether, pyrrolidone, glycerol, diethylene glycol, 1,2-hexane
- the ink composition also includes a dispersant.
- a dispersant is styrene acrylic copolymers.
- Forming embodiment(s) of the inkjet ink composition includes providing or making the ink vehicle, and adding the effective amount of pigment red 168 thereto. It is to be understood that generally the pigment red 168 contributes to the scarlet hue exhibited by the ink composition disclosed herein.
- the effective amount of pigment red 168 has a pigment load sufficient to provide an absorbance maxima, ranging from about 0.075 to about 1.2 at a 1:2,500 dilution of the red ink, at a wavelength maxima ranging from about 480 nm to about 580 nm.
- the amount of pigment red 168 in the ink composition ranges from about 1 wt. % to about 15 wt. %.
- the amount of pigment red 168 may range from about 2 wt. % to about 8 wt. %, or from about 3 wt. % to about 6 wt. %.
- the pigment red 168 may be in the form of solid pigment particles. Generally, an average particle size of the pigment red 168 ranges from about 30 nm to about 200 nm.
- effective amounts of other pigments may be added to the ink vehicle.
- other pigments include yellow pigment(s), scarlet pigment(s), magenta pigment(s), or combinations thereof.
- the ink composition is established on at least a portion of a substrate to form an image.
- the amount of the ink composition established depends, at least in part, on the desirable image to be formed.
- the image may include alphanumeric indicia, graphical indicia, or combinations thereof.
- the inks may be established substantially simultaneously or sequentially via inkjet printing techniques.
- suitable inkjet printing techniques include piezoelectric inkjet printing, thermal inkjet printing, or combinations thereof.
- suitable substrate materials include, but are not limited to plain papers, microporous photopapers, coated papers, glossy photopapers, semi-gloss photopapers, heavy weight matte papers, billboard papers, digital fine art papers, calendared papers, vinyl papers, or combinations thereof.
- Printing of the inkjet ink composition(s) disclosed herein results in image(s) having colors ranging from orange to reddish scarlet. It is to be understood that by altering component(s) or amounts of component(s) in the ink vehicle, the resulting color of the printed image may be changed.
- the color of the printed image formed with embodiment(s) of the ink composition may also depend, at least in part, on the pigment loading, the printing technology used (i.e., solvent based or water based), or combinations thereof.
- the image(s) formed from embodiments of the ink composition generally exhibit good to excellent lightfastness, good to excellent ozonefastness, enhanced chroma, and/or combinations thereof.
- the vehicle for each of the inks included about 0.7 wt. % water soluble polymer, about 0.5 wt. % non-ionic surfactant, about 3 wt. % glyceryl polyoxyethyl ether, about 6 wt. % 2-pyrrolidone, about 5 wt. % glycerol, about 4 wt. % 1,2-hexanediol, about 0.19 wt.
- the inks were printed on three different types of media, including heavy weight matte paper, microporous photo paper, and digital fine art paper. The ozonefastness and indoor lightfastness were measured for each of the printed inks.
- the images formed with ink made with pigment red 168 exhibited medium to beyond excellent (i.e., no fade) ozonefastness and excellent lightfastness on each of the media types.
- the PR254-Type 1 and PR254-Type 2 exhibited worse ozonefastness results when compared to the lightfastness results.
- the results for the pigment red 177 varied, depending on the type of media used.
- Pigment red 208 exhibited generally poor to medium results on each of the media types.
- Chroma was measured with a Graytag Macbeth SpectroScan.
- the term “Good” indicates that the chroma value was above 90; the term “Medium” indicates that the chroma value was between 80 and 90; and the term “Poor” indicates the chroma value was less than 80.
- the combination of the lightfastness, ozonefastness, and chroma results indicates that the ink including PR168 offers a variety of enhanced properties.
